JOHN A. CLUXTON, OF BENTONVILLE, OHIO.

DRAG-SAW.

SPECIFICATION forming part of Letters Patent No. 226,718, dated April20, 1880.

Application filed February 25, 1880.

To all whom it may concern:

Be it known that I, J OHN A. OLUXToN, of Bentonville, in the county ofAdams and State of Ohio, have invented certain newand usefulImprovements in Drag-Saws; and I do here by declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference markedthereon, which form part of this specification.

The nature of my invention consists in the construction and arrangementof a sawing-machine for cross-cutting logs, &c., for stovewood or otherpurposes, as will be hereinafter more fully set forth. 7

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in which-Figure 1 is a perspective view of my sawing-machine. Fig. 2 is a centralvertical section of the same, and Fig. 3 is adetail view of thesaw-head.

The frame of my machine is composed of two parallel sills, A A, uponwhich are standards or uprights B B, suitably braced and gornected attheir upper ends by cross-pieces The inner edges of the standards B Bare grooved vertically, and in said grooves is placed a sash, D, whichcarries the saw, and this sash is suspended by means of a cord,

a, passing upward and over pulleys b b in the top of the frame, and thendownward to a crank, E, at the side of the frame, so that the sash maybe raised and lowered at pleasure.

' The sash is held at any point by means of a ratchet-wheel, d, on thecrank-shaft and a pawl, e. I

F represents a pendulum, provided at its upper end with a bail, Gr, bentforward and hung upon a plate or bar, f, near the top of the sash, so asto allow the pendulum to swing freely.

In the lower end of the pendulumF is pivoted a short arm, H, to whichthe saw I is rigidly attached.

The arm His on each side provided with rollers h h, and at the heel orrear end may be provided with a single roller.

The side rollers, h h, bear against guideboards J J, attached to theframe, and the roller at the rear, when used, bears against a bottomboard, K, arranged on a proper curve at the rear ends and between theguide-boards J J, whereby the saw is guided true and without anyunnecessary friction.

At the front end of the saw is pivoted an arm, L, which is perforatedand passes through a slot or mortise in a long arm, M, and therepivoted, the rear end of said long arm being pivoted in the pendulum F.

N is a curved arm, rigidly attached to the pendulum near its lower end,and to which the handle 0 is adjusted and secured, the front end of thehandle being pivoted in the pendulum.

P P are dogs connected to the standards B B, for holding the machine tothe log.

By the construction of the machine the operator can get close to hiswork, which is always desirable.

' The guide-rollers steady the saw, and a weight, R, on thebail G at thetop gives a back motion.

The connection L at the point of the saw is to be raised or lowered tosuit the size of the log, and the handle can be adjusted up or down tosuit the height of the operator.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, isv 1. In a sawing-machine, thesliding sash D, suspended and held at any desired point in the frame bymeans of the cord a, crank E, ratchet-wheel d, and pawl e, incombination with pendulum F, hung on bar f, weight Gr, curvedguide-boards J K, saw-head H, and saw I,allconstructed and arranged tooperate substantially as herein set forth.

2. In a sawing-machine, the combination of pendulum F, hung loosely uponbar f and provided with weight R, with the sliding and suspended sash D,adjustable arm M, connection L, saw Land saw-head H, all constructed andarranged to operate as and for the purposes set forth.

3. The within-described sawing-machine, In testimony that I claim theforegoing as consisting, essentially, of frame A B, susmy ownI affix mysignature in presence oftwo 1o pended and sliding sash D, swingingpendu- Witnesses. 1
